MACHINERY FOR WINDING WARPS UPON THE BEAM.

Specification of Letters Patent No. 25,266, dated August 80, 1859.

To all 'whom it may concern:

Be it known that I, DANIEL I-IUssEY, of Nashua, in the county ofHillsboro and State of New Hampshire, have invented a new and useful orImproved Mechanism for Winding Yarn upon a Beam or Roller with a UniformVelocity; and I do hereby declare that the same is fully described andrepresented in the following specification and the accompanyingdrawings, of which- Figure l, is a side elevation, and Fig. 2, a rearelevation of the same. Fig. 3, is a longitudinal section of themechanism hereinafter described, and termed the compound motion.

The nature of the said invention consists in a. peculiar combination formaintaining uniformity of wind or surface speed of wind on the yarnbeam.

IVarp dressers have hitherto been constructed so that the speed ofwinding the yarn upon the beam, had to be varied by the operator. Thebeam being driven at a uniform speed, would cause the wind of the yarnor quantity wound thereon to constantly increase in diameter. Theaccumulation of yarn in like proportion would increase, the length ofyarn which would be drawn forward or made to pass a given point in agiven time. In ordinary cases, it is desirable to wind up the yarn asfast as it will properly dry. Should it run in a damp state on the beam,the yarn would be liable to injury by mildew or otherwise. In order toguard against this cones or cone pulleys have been constructed andapplied so that the operative could change the driving belt of the beamfrom pulley to pulley and thus alter the speed of the beam. Othersimilar contrivances have been used such as a friction pulley acting onthe periphery of another pulley which could be moved nearer to orfarther from the center of the first pulley and thus vary the speed ofthel beam. But unless the operative gave all or a greater part of histime and attention to the matter and moved the belt or substitute justin proportion to the increasing size of the beam there would be avariation in the speed of the yarn. Generally, he

would move the belt or substitute at long intervals and t-he yarnfrequently run on damp and caused more or less damage. My improveddresser machinery is so constructed that notwithstanding the variationin the wind of the yarn, the yarn will be l wound up with a uniformvelocity. Furthermore, the degree of velocity can be varied at will tosuit the variations in the hygrometric or thermometric changes in theatmosphere. Vhatever may be the speed adopted for the winding of theyarn it will remain uniform until the machinery may be arranged toproduce another rate of speed.

In the drawings, A denotes the yarn beam; B, the rear guide roller; C,the steam heating cylinder, and, D, the fan blower of a common warpdresser, the remainder of which is not exhibited.

The yarn in its passage from the heating cylinder, C, under theguide-roller, B, and to the yarn beam, A, is shown at, Y, in Fig. l, bya red line.

The driving shaft of the mechanism for operating the yarn beam isexhibited at, E. It carries a vertical disk wheel, F, against whose faceor side the periphery of a horizontal friction wheel, G, rests, thewheel, F, being borne against the wheel G by a spring a.. The wheel G isfixed on a vertical shaft I-I and so as to be capable of sliding freelyand longitudinally thereon and on al spline or feather connection bywhich the rotation of the wheel is made to produce that of the shaft.The upper end of the shaft carries a bevel pinion c, which drives atrain. of gears al, c, g, it, the latter of which is fixed on the shaftof the yarn beam A.

From the above, it will be seen that when the shaft E, is put inrevolution, it will cause the yarn beam to revolve and wind up the yarn.It will also be seen that the rates of movement of the periphery of theguide roller B, will correspond with or be equal to that of theperiphery of the amount or mass of yarn wound on the yarn beam at anytime; also, that in proportion as the roll of yarn on the beam mayincrease in diameter, the draft or velocity of movement of the yarn willbe increased. The mechanism to be described overcomes the gradualincrease of the draft and renders t-he draft uniform.

A vertical slide rack, K, (see Figs. l and '2) carries a projection orfoot c', which enters a groove 7c, `made in and around the hub of thewheel G. A pinion Z, on a horizontal shaft m, (see Figs. l and 3,)engages with the said rack. The shaft m, extends through two tubularshafts fn, 0, which respectively carry bevel gears p, g, arranged asshown in the drawing and both made to engage with a bevel pinion, 7,carried by an arm, s, projecting from the shaft, m;

The shaft, m, and that of the guide roller B, have cone pulleys, t, u,applied to them around which a crosse band fu, extends. Furthermore, thegear, g, and its shaft, 0, are rotated by the driving shaft actingthrough a pulley w, an endless band m, a pulley, y, and a train ofgears, e, a, b, c, the latter of which is xed to the side of the bevelgear q. The-said gears, p, g, together with the pinion a, the arm, s,and shaft, m, with their accessories are what is usually termed or maybe called a compound mo- So long as the two gears p, g, revolve at thesame speed, the pinion will revolve, and the arm, s, will be stationary,but in case, the outermost gear, p, is moved at a faster speed than theother its action on the pinion will be such as to move its supportingarm so as to turn the shaft, m, in a manner to cause its pinion, Z, todepress the rack K, and thereby force the wheel G, downward nearer tothe center of the wheel F, whereby the degree of rotary motion of orsurface of the said roller and as any increase thereof will be attendedby a depression of the wheel, Gr, toward the center of the wheel F, thespeed of the yarn beam will be checked so as to render the rate ofsurface movement of the roll of yarn thereon correspondent with that ofthe periphery of the guide roller, B. By means of the set of conepulleys, the rate of movement of the guide roller may be varied for toaccomplish such, we have only to change the belt of the pulley into suchgrooves of them as may be desirable to effect the proper rate of speedfor the wind of the yarn on the beam.

Having thus described my invention what I claim is as follows:

I claim the peculiar combination for maintaining uniformity of wind orsurface speed of wind on the yarn beam; the same consisting of thefriction wheels, Gr, F, the lifter rack, K, the pinion, Z, and thecompound motion mechanism or their mechanical equivalents; the wholebeing applied to the yarn guide roller and the mechanism for adjustingthe yarn beam, substantially in manner and so as to operate asspecified.

In testimony whereof I have hereunto set my signature.
